The "Yo" App Was So Last Week, Now We're All "Hodor"-ing Everyone

Remember that Yo app from last week? The one that did nothing but send a "Yo" to people you may or may not actually know? Well now you can send a friendly "Hodor" in much the same way! I don't know about Hodor but that makes Hodor feel very Hodor, if you ask Hodor.
